These sub-interfaces are configured with IP addresses and OSPF. A single physical interface has multiple sub-interfaces (VLAN interfaces). The MTU of the physical interface has been increased, but the MTU of the VLAN interfaces has not been changed. The MTU remained unchanged when I checked the OSPF hello packets in Wireshark.
